This would be limited to win-x86 since .NET doesn't even run on win-arm anymore.

Some things that would need to be done:

  • Fetch libnethost.lib for win-x86.
  • Build the native module for win-x86.
  • Do some minor porting work in Vezel.Ruptura.Injection.
  • Port the hook gate machinery.
  • Add a sample that tests win-x64 -> win-x86 injection.

Switch ruptura_main from stdcall to cdecl.
dd5c06d 
We don't use CreateRemoteThread to invoke it directly, so using cdecl simplifies
finding the symbol for 32-bit (no stdcall name mangling).

Part of #5.

The hook gate needs to be ported to 32-bit:

ruptura/src/memory/Code/FunctionHook.cs

Line 297 in b2bd417

throw new NotImplementedException(); // TODO: Implement 32-bit hook gate.

The Zig bug has been recognized as a blocker for Tier 1 support, so seems likely it might be fixed in Zig 0.12.0.

This will need to be addressed as well:

ruptura/src/injection/IO/ProcessMemoryStream.cs

Lines 3 to 5 in 8681fd0

internal sealed unsafe class ProcessMemoryStream : Stream
{
// TODO: Review some of the casts here.

I've decided to go forward with #98 so this is only blocked on that now.
